This is a very heavy duty, bright flashlight. I love the fact that it is rechargeable. It also comes with a battery adapter so that you can use regular batteries if necessary. The super bright LED light has a zoom function that gives you either a wide swath of light, or an ultra tight pin light. It charges very quickly, and comes in a very nice, sturdy carrying case. Another great feature is that the back of the handle has a glass breaker on it. I have not tried to break any glass with it, but the flashlight is heavy enough to put force behind a strike to shatter glass. Overall this is a great tool to keep handy in the car for an emergency.
